GASOLENE-BU RN ER.

SIECIFIGATION forming part of Letters Patent No. 739,144, dated September 15, 1903.

Application filed March 14,1903- To all whom it may concern.-

Be it known that I, ATWELL J. BLACKFORD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Gasolene-Burners, of which the following is a specification.

My invention relates to improvements in gasolene-burners, and pertains to that class of burners in which the gasolene is vaporized or evaporated in the presence of atmosphere and fed by gravity through a tube to the lower end of the burner, the upper end of the burner being provided with a collecting-hood which is connected with the point of evaporation through themedium of a hot-air-conducting pipe. In this form of burner in order to enable it to be used successfully it has been necessary to provide what is known as a subfire-burner at the lower end of the burner-tube proper.

In a burner constructed as just described it requires considerable time to obtain a normal or full-sized flame, owing to the fact that it cannot be produced until the burner has become sutiiciently heated at its upper end to radiate heat for the air in the collectinghood to be conducted therefrom to the point of evaporation. Especially is this true when the temperature of the room in which the stove is being operated is cold. In this class of burners the heat produced by the subfire is of no practical importance in assisting to produce a normal flame in the burner proper, but only serves to radiate heat at the lower end of the burner-tube, and thus prevent condensation of the evaporated vapor at that point; also, in the operation of burners of this kind the subfire is lighted practically concurrently with the lighting of the main burner or fire, and the heat produced thereby passes out through the central tube of the burner proper.

The object of my present invention is to provide means whereby the heated air from the subfire is directly conducted into the hotair-conducting tube,and thereby directly con ducted to the evaporating or vaporizing point, whereby warm air is practically instantaneously furnished at the vaporizing-point when the burner is lighted and which is found to produce a normal or full-sized flame several Serial No. 147,772. (No model.)

minutes earlier than in a burner not provided with this direct heat-conducting means from the subfire.

The accompanying drawing is a vertical sectional view of a burner embodying myinvention.

-Referring now to the drawing, 1 indicates the burner proper, 2 the outer burner-tube, and 3 the inner or central burner-tube.

Surrounding the upper end of the outer burner-tube 2 and located below the burner 1 is a heat-collecting hood 4, and this heatcollectinghood 4 is connected, through the medium of a tube 5, with the evaporator 6, and the evaporator is connected with the outer burner'tube 2 at its lower end by a tube 10 and furnishes the vaporized or evaporated gasolene mixed with the proper quantity of air, which passes upward to the burner 1, where it is lighted.

Situated within the lower end of the burner 2 is a subfire-burner 7, and in the ordinary construction of stoves of this character the burner is formed directly in the Wall of the inner or central tube 3 in a manner well understood by those skilled in the art.

' Thus far I have described the ordinary form of burner and will now proceed to describe my improvement.

My improvement consists in connecting the subfire 7 by means of a tube directly with the heat-conducting tube 5, and, as here shown, I make this connection through the medium of the central tube 3 and the laterally-extending tube 8,which connects with the upper portion of the central tube and passes through the outer burner-tube 2 and through the heat-collecting hood 4 directly into the heat-conducting tube 5. From this description and as indicated by arrows it will be seen that the heat produced by the subfireburner 7 is directly conducted into the heatconducting tube 5 and immediately conducted to the evaporator 6. In the operation of burners of this character the subfire (as previously stated) is lighted practically concurrently with the lighting of the main fire or burner 1 in a manner well understood by those skilled in the art, and hence heat is immediately conducted from the subfire directly to the evaporator 6 without the necessity of waiting until the hood 4 at the upper end of the burner becomes sufliciently heated to furnish hot air in the usual way to the evaporator, and thus very materially shorten the time required to produce a normal or full-sized main flame at the burner 1. As well known in this class of burners, when the burner 1 is first lighted it.flickers and produces very little heat, and hence considerable time is required to heat up the burner and to heatitsufticiently to furnish sufiicient warm air through the medium of the hood 4 to the evaporator 6. By connecting the subfire directly with the evaporator, as here shown, the burner will work to produce a normal flame very quickly as compared with the old construction and also produces a burner which will work successfully and quickly in the coldest climate, which has been an objectionable feature of the ordinary burner constructed in the manner hereinbefore explained.

\Vhile I here show the subfire A formed directly in the central tube 3 and having the central tube 3 forming a part of the means for conducting heat therefrom and whileI show the usual heat-conducting tube 5 also forming a part of the conducting passageway for the heat from the subfire to the evaporator, it will be readily understood that this construction can be modified and changed without departing from the spirit and scope of my inventionpvhich is, broadly considered, the use of a subfire which furnishes heat that is directly conducted to the evaporator for the purposes hereinbefore explained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A burner of the character described including a main burner, an evaporator connected therewith, and a subburner communicating with and furnishing Warm air to the evaporator.

2. A burner of the character described, including a main burner, an evaporator connected therewith, means at the upper portion of the burner for heating air, an air-conducting tube connecting the said means with the evaporator, and a subburner having a passage-way connecting it with the said hot-airconducting tube.

3. A burner of the character described including a main burner havinga central tube, an evaporator operatively connected with the main burner, the main burner provided with means for heating air, a tube connecting the said air-heating means with the evaporator, a subburner formed in the central tube of the main burner, and a passage-way connecting the said central tube with the said hot-airconducting tube.

4. A burner of the character described including a main burner having a central tube, an evaporator operatively connected with the main burner, a hood located below the main burner and exterior thereof, a hot-air tube connecting the said hood with the evaporator, a su bburner located within the central tube, and a laterally extending tube passing through the said hood portion and connecting the hot-air-conducting tube and the said central burner-tube.

5. A burner of the character described, including a main burner, an evaporator connected therewith, the main burner having a central tube provided with a subburner, and an air-conducting tube connecting the said central tube with the evaporator.

6. A burner of the character described including a main burner, an evaporator, connected therewith, and a subburner located at a point between the main burner and the evaporator, the subburner having a hot-air passage-way in communication with and supplying warm air to the evaporator.

7. A burner of the character described, including a main burner, an evaporator connected therewith, and a subburner having a hot-air passage-way connecting it with the evaporator and furnishing warm air thereto.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
